Researchers at Johns Hopkins Hospital found that 24 models of
pacemakers and implanted defibrillators (see table) seemed to be
safe for use in a standard MRI machine. Keep in mind that the
Hopkins protocol included temporarily reprogramming implanted
devices for the duration of the MRI, turning off defibrillators'
shock function, reducing the energy of the MRI, continuous
monitoring with an electrocardiogram during the scan, and making
sure that equipment for restarting the heart and performing CPR
were immediately available. This study does not give a green
light for MRIs in everyone with a pacemaker or implanted
defibrillator.

cholesterol levels in blacks than in whites. The difference was
not attributable to one single reason, but it may mean that
blacks need to take another drug in conjunction with a statin.
